16-port Web Smart Gigabit Switch

The Black Box LGB2118A-R2 is a 1U rackmount switch delivering sixteen 10/100/1000 Mbps RJ45 ports and two SFP uplinks for fibre connectivity. It runs a web-smart operating system accessible through HTTP, HTTPS, SNMP, Telnet or SSH. An 8K MAC address table supports Layer 2 forwarding for small to mid-size networks.

Suited for managed edge deployments

This switch fits administrators who need configurable QoS, VLANs and energy-efficient 802.3az operation without a full Layer 3 feature set. Buyers who require routing between VLANs, dynamic routing protocols or a larger MAC table should look at a different class of device.

8K MAC address table capacity

The 8K entry table determines how many unique endpoints the switch can learn and forward traffic to without flooding. Networks that approach this limit will experience increased broadcast traffic and should verify the figure against their endpoint count.
